I bought a new vehicle, what should I do

I bought a 2005 model 206 1.4 HDI station wagon 2 weeks ago. The vehicle is at 126000km. What kind of maintenance should I pay for filters, oil etc. Should the mosaic filter change? by the way, which oil do you recommend? when the timing should change etc. a to z, please let someone know help

Oil + oil filter + air filter + diesel filter is suitable as standard, & nbsp;
